With a variety of products, Google certainly needs to maintain its own security and that of its users. That's why they have a 'cyber security' called the Threat Analysis Group (TAG).
Google's Threat Analysis Group (TAG) mission is quite challenging, namely understanding and combating targeted hacking and government-supported hacking and online threats to Google and its users.
The main task of TAG is to detect and thwart threats, and also to warn users and customers who are potential targets. Coverage varies, including keeping Gmail, Drive, and YouTube secure.
The TAG team works globally and there are at least 270 hacker groups under surveillance, including government-backed hacker groups, in more than 50 countries.
These groups have many purposes, including gathering intelligence, stealing intellectual property, targeting dissidents and activists, carrying out destructive cyber attacks, or coordinating disinformation.
They also use the collected intelligence to stop malware and phishing activities that threaten Google's infrastructure and its users.
One form of warning that TAG issues is if they detect a state-sponsored phishing attempt to their users. These users are usually targeted via email, and phishing attempts are made to obtain personal data, such as passwords or other personal information that will later be used to hijack the target's account.
In addition, TAG is also one way for Google to stop the spread of disinformation networks that use its services to spread disinformation.
The number of Google products that must be handled is considered by Shane Huntley, TAG's boss, when speaking to the media on Friday (18/3) as an advantage. Because when they find a threat, the information is disseminated and implemented in various Google products.
